I know its hard to mess up a test with that Hanna ALK Checker (i have it too) but that much variation in a tank the size of yours (which would take a few bags (or boxes even) just seems very strange to me.

I've only tested the tank twice for dKH;
1) SG 1.022 and the number was 289ppm
2) SG 1.024 and the number was 289ppm again

Maybe I just got all the dKH additives from the batch? I'll keep testing it as the system breaks in some more.
